However we know from practical experience our products can remain usable for 1-2 years or longer if they are properly handled and stored. Service Complete PANTONE mixing recommendations. Ink formulation systems, mixing systems and dispensing systems are possible in different expansion levels. Base ink basis for mixing recommendations: - UVALUX U3-P... PANTONE base inks - UVALUX U3-Z... high intensity monopigmented base inks Practice Remarks Printing Materials We recommend using ester and ketone resistant rollers (EPDM-material). The inking roller, rubber blanket and printing plate have to be resistant against UV-inks and UV-detergents (see manufacturers instructions). Fountain Solution Approved fountain solution parameters: a) ph-value: 4,8-5,2 b) Water hardness: 9-12 dh We recommend the use of temperature controlled ink ducts and fountain solution. Information about Light Resistance All light resistances are indicated according to the blue wool scale (BWS) and are based on the product specifications of our pigment suppliers. Light resistance can change when mixing inks and when printing halftone. Depending on the mixing ratio and on the fineness of the screen the light resistance can be lower than the pure solid colour. Temperature Resistance All inks of this series are suitable for heat sterilising at 121 C/30min. In addition the individual colours have the following 06/ Page 3 of 10

We can not make any statements concerning food packaging legislation of countries outside the EU. 06/ Page 6 of 10

7 Regulation (EC) No. 1935/2004 requires that the one responsible for the placing on the market of a packaging article must have an appropriate documentation available to demonstrate the compliance with the rules related to food processing and distribution. Not only the used materials have an influence on the food-legislation related properties of a packaging. The production process of the packaging has a significant impact as well. Therefore we recommend that you send your finished products to a recognized analytical institute for examination and certification. That way you can prove that your products comply with the legal requirements. The transfer of substances from the packing into the filling is called migration. The following production parameters have a significant influence on the grade of migration: - correct processing, especially the complete through-cure of the ink film - type of substrate and substrate thickness (sufficient barrier effect of the substrate) - prevention of a direct contact of the printing ink with the food - use of low-migration printing inks The UVALUX U3 Ink Series has no special low-migration formulation. However various analyses of metal packaging have shown that it is possible with this ink series to achieve conformity with EU packaging legislation. The Nestlé guidance note dated 2nd February 2012 contains an exclusion list for photo-initiators which is explicitly not valid for metal substrates. The UVALUX U3 Ink Series is formulated in accordance with the Nestlé Guidance Note on Packaging Inks. The UVALUX U3 Ink Series is formulated in accordance with the Swiss ordinance on materials and articles intended to get into contact with food. The UVALUX U3 Ink Series is formulated without free bisphenol A and without bisphenol A based raw materials (BPA-NI). Declaration of Composition and Product Declaration As there are no specific regulations concerning printing inks and varnishes Zeller+Gmelin -like other ink suppliers- is obliged to follow regulations in the EU not directly related to printing inks. Regulation (EU) 1935/2004 Article 3 of the Regulation 1935/2004 (impact on food) demands, that materials and articles do not transfer their constituents 06/ Page 7 of 10

8 to food in quantities which could endanger human health or bring about an unacceptable change in the composition of the food or bring about a deterioration in the organoleptic characteristics thereof. We urgently advise you to use for printing on food packaging only printing inks/lacquers which we specifically recommend for this application and which have a low-migration formulation. A possible impact on the quality of food does not solely depend on the printing ink/lacquer itself but is depending on the complete production chain (ink laydown, UV-power, substrate, etc.). For this reason we can generally not confirm a compliance to Regulation 1935/2004 only based on the composition of the ink/lacquer. Based on Article 17 (traceability) material and articles shall be ensured at all stages in order to facilitate control, the recall of defective products, consumer information and the attribution of responsibility. All raw materials for ink/lacquer batches at Zeller+Gmelin are documented in writing on the Formula Component Report. Based on the batch number every raw material can be clearly traced back to the raw material batch. Regulation (EU) 2023/2006 This so called GMP regulation (Good Manufacturing Practice) defines the requirements on the different participants in the manufacturing process of materials and articles intended to come into contact with food. It requests a system for quality assurance, control and documentation ( 5-7). The EuPIA defined the requirements on printing ink manufacturers in the EuPIA-GMP. Regulation (EU) No 10/2011 and Regulation (EU) 1282/2011 Regulation EU 10/2011 and 1282/2011 establishes the specific rules for plastic materials and articles to be applied for their safe use and repeals Commission Directive 2002/72/EC of 6 August 2002 on plastic materials and articles intended to come into contact with foodstuffs (2). In this regulation, the so called PIM (Plastic Implementation Measure) limits are set for substances, which are allowed to be in direct contact with food and are allowed to migrate into the food up to the level listed in Annex I. Substances used in printing inks must not (with few exemptions) get in direct contact with food and are therefore not listed in Annex I. Paragraph (30) states, that Coatings, printing inks and adhesives are not yet covered by a specific EU legislation and therefore not subject to the requirement of a declaration of compliance. For the migration of non authorised substances through a functional barrier into food a limit of 0,01 mg/kg (10 ppb) is set. Substances that are mutagenic, carcinogenic or toxic to reproduction should not be used without previous authorisation in food contact materials or articles and should therefore not be covered by the functional barrier concept. CEPE / EuPIA Exclusion Policy CEPE is the European Council of producers and importers of paints, printing inks and artists colours whereas EuPIA is the European Printing Ink Group of CEPE. The printing ink industry voluntarily came up with the Exclusion Policy for specific substances many years ago. Zeller+Gmelin is an active member in the EuPIA and subgroups. The raw materials used by Zeller+Gmelin for the formulation of our printing inks/lacquers meet the guidelines of the CEPE / EuPIA Exclusion Policy. This means that CMR 1A and 1B 06/ Page 8 of 10

9 substances (cancerogenic, mutagenic and reprotoxic) plus T (toxic) and T+ (very toxic) are not used in our printing inks/lacquers. Heavy Metals CONEG stands for Coalition of North-Eastern Governors in the USA. One of their legislations, adopted by 18 states as of 1998, requires reductions in the amount of the four heavy metals mercury, lead, cadmium, and hexavalent chromium in packaging and packaging components sold or distributed in their member states. For Zeller+Gmelin printing inks/lacquers the limits for heavy metals as listed in the CONEG-Regulation (USA) are met. The Euro Norm 71.3 refers to the max level of heavy metals in childrens toys. For Zeller+Gmelin printing inks/lacquers the limits for heavy metals as listed in the DIN EN 71-3 are met. Heavy metals are no part of our formulations. Hazardous substances Substances mentioned in the directive 2002/95/EC (RoHS) and directive 2011/65/EC are not intentionally used in our formulations printing inks/lacquers. SVHC-substances (substances of very high concern): In our products no substances are used which are classified as CMR 1A & 1B, PBT (PBT pollutants are chemicals that are toxic, persist in the environment and bioaccumulate in food chains), vpvb (Substances that are potentially very persistent and very bioaccumulative) und endocrine disruptors (artificial hormones). Furthermore we confirm that our printing inks/lacquers are in accordance with the EC regulation 1895/2005 (repeals the guide line 2002/16/EC). ISO 9001 The production site of Zeller+Gmelin / Germany is certified according to DIN EN ISO 9001:2008 and DIN EN ISO 14001:2005 (corresponds to EN ISO edition Nov. 2004). Swiss Ordinance This ordinance regulates materials and articles intended to come into contact with food. On the ordinance was changed to include regulations concerning printing inks. Since only packaging which has been produced with conforming printing inks may be supplied to consumers. We urgently advise you to use for food packaging which is subject to this regulation only printing inks/lacquers which we specifically recommend for this application and which have a lowmigration formulation. Please note: According to applicable law the manufacturer of the finished article and the filler have the full legal responsibility to ensure that their product is fit for its intended purpose and complies with the applicable rules (not the supplier). Please also consider the relevant publications of the European Printing Inks Association EuPIA ( 06/ Page 9 of 10

10 There are many types of final packaging and the printing ink/lacquer is only one constituent. Since the parameters in the printing, packing and storage processes are not under the control of the printing ink manufacturer, the printing ink suppliers are not able to issue certificates or declarations of compliance which cover the legal responsibility of the entire packaging chain (Text from EuPIA-PIFOOD May 2007). The statements made in this declaration are according to our current knowledge. They do not absolve the user from its own responsibility to ascertain that our products are suitable for his application. 06/ Page 10 of 10
